Em 2015, o estado produziu 8 milhões de bovinos e bubalinos, 296 mil suínos e 158,9 mil caprinos. As fronteiras socioeconômicas terão uma melhora significativa com a utilização de resíduos gerados na atividade rural para a geração de energia, assim como para a redução dos prejuízos ao meio ambiente, ocasionados pelos resíduos produzidos. Diante do exposto, o objetivo do presente trabalho foi avaliar o potencial de produção de biogás para a geração de energia, por meio da fermentação de resíduos oriundos da agricultura e pecuária do estado do Tocantins. A metodologia utilizada foi a revisão bibliográfica, a sistemática, a descritiva e a explicativa. Verificou-se, com este artigo, a relevância social, ambiental e econômica da inserção da energia produzida a partir dos resíduos agropecuários na Matriz Energética Brasileira. Ainda que tenham custos para instalar o sistema no Estado, a utilização de digestores fermentativos é uma alternativa para diminuir os problemas com a destinação inadequada dos resíduos agropecuários, além de ser uma forma de energia limpa, este método possuí uma fonte de recursos com o comercio dos créditos de carbono, devido a não emissão do gás metano.   Palavras-chave: resíduos agropecuários, energia, biogás.   STUDY ON THE POSSIBILITY OF BIOGAS PRODUCING FROM AGRICULTURAL WASTE THE STATE OF TOCANTINS   ABSTRACT: Beef and dairy cattle growing is one of the biggest production in the State of Tocantins - Brazil, favored by weather conditions. In 2015, the state produced 8 million cattle and buffalo, 296,000 pigs and 158,900 goats. The socioeconomic boundaries will have a significant improvement with the use of waste generated in rural activity for the generation of energy, as well as the reduction of environmental damage caused by the waste produced. Given the above, the objective of the present work was to evaluate the potential of biogas production for energy generation, through the fermentation of residues from the Tocantins state agriculture and livestock. The methodology used was the literature review, the systematic, the descriptive and the explanatory. This article verified the social, environmental and economic relevance of the insertion of energy produced from agricultural residues in the Brazilian Energy Matrix. Although they have costs to install the system in the state, the use of fermentative digesters is an alternative to reduce the problems with the improper disposal of agricultural residues, besides being a form of clean energy, this method has a source of resources with the trade. carbon credits due to non-emission of methane gas.   Keywords: agricultural residues, energy, biogas.

At the beginning of the 20th century, urbanization and occupation of privileged spaces at the expense of “lowland” spaces and close to a floodplain. The “lowlands” were occupied by a population, mostly with socioeconomic needs, forming housing groups susceptible to flooding and flooding. To bring the recognition of rights to these occupants, a land regularization work was carried out by the Federal University of Pará - UFPA, together with public entities from the State and the Union. The article aims to present and compare the degree of socio-environmental vulnerability in the area of land C of UFPA in the municipality of Belém, object of land regularization activity, applying indicators and indices related to social, economic, legal and environmental issues. The results show that the degree of vulnerability is high in the years surveyed, concluding that the legal regularization work carried out in the area was only patrimonial, in order to transfer responsibilities for land use to the beneficiary residents and the recognition of the right of that title by law. . Effective land regularization work should involve a set of bodies responsible for the social, environmental, urban and land areas so that, in a concatenated and long-term manner, the work carried out is carried out so that the results are captured by the indicators and that the data decrease the degree of socio-environmental vulnerability in the studied area.

Energy Reforms

Subject Efforts to reduce Mexico's dependence on fossil fuels. Significance President Enrique Pena Nieto's energy reforms aim to boost investment in Mexico's hydrocarbons industry. However, they are also intended to reduce the country's reliance on fossil fuels by developing the biofuels sector and renewable energies, such as solar, wind and geothermal power. Among the issues that the new legislature, which starts on September 1, will have to address are three pieces of secondary legislation that are key to achieving the government's goal of increasing the share of renewables in Mexico's energy matrix. Impacts Unless the state improves and expands transmission capacity, development of the sector will be limited. Renewables will face stiff competition from the hydrocarbons sector, which has received much greater incentives for investment. Clean energy laws will continue to encounter opposition from businesses if power derived from renewables does not become cheaper.

The article analyzes the institutional problems of the water supply and wastewater system of Ukraine. Government-created institutions have a direct or indirect effect on the state and development of the water supply and wastewater sector, determine the processes for its modernization, as the water supply and wastewater sector itself has a certain influence on the institutions, creating the basis for their modernization, transformation or liquidation. The author argues that in order to be effective in implementing the state policy in the field of water supply and wastewater, it has to be consistent with the goals of state economic policy in other areas - social, environmental, tax, energy, financial and economic, housing, national security, etc. The article analyzes how the uncoordinated state policy of the country in the social, environmental, tax, financial, energy, foreign economic sphere affects the sphere of water supply and wastewater and its consequences. The author defines the problems of institutional provision of state policy in the field of water supply and wastewater and describes them. The author argues that the influence of institutional problems on the state and development of the water supply and wastewater system is so great that, no matter how efficient the management and regulation in the field of water supply and wastewater, the result will not meet expectations. In the article the author suggests ways of solving some institutional problems in the field of research.

The latest directives of the Energy and Environment Policy of the European Union (EU) established a new framework for renewable sources (Directive EC 28/2009; European Commission, 2009). The Italian Energy Action Plan of 2010 set a target of at least 17% of total energy generated from renewable sources by 2020. In this context biogas from waste and biomass is a potential energy source that can be used for the production of heat, electricity and fuel. The objective of this work was to determine the potential energy production from anaerobic digestion of animal wastes and agricultural residues in Friuli Venezia Giulia (Nord-East Italy). For an assessment of biogas as an energy source, based on direct conversion by agricultural farms, it is important to establish the amount of the waste. In this study, biogas amount which can be obtained was calculated for all municipalities in the Friuli Venezia Giulia Region (North-East of Italy) by using the number of livestock animals, the cereal area for agricultural residues and also considering various criteria such as the rate of dry matter and availability. The calculated regional biogas potential is about 187 (N)Gm3 when using animal waste, straw and corn stalk. The potential of biogas energy equivalent of Friuli Venezia Giulia is about 3 600 TJ (LHV) may be able to replace 2.6% of final energy consumption in Friuli Venezia Giulia (3 339 ktoe) and about 10% of the final electricity consumption (864 ktoe) considering an electrical efficiency of 30% with the biogas engine.

Abstract BackgroundHeavy dependence on firewood, associated with the demographic factor, logging, agricultural expansion and the repercussions of political instability are presented as factors of deforestation and forest degradation in Côte d'Ivoire. Faced with this situation, the country has been striving for many years to put in place a policy favorable to the protection of the environment through the promotion of alternative energy sources to firewood. However, observations are emerging in the field of bakery activity and call into question the social logic of the choice of baking energy. The bakery sector is presented as one of the main contributors to the erosion in the capital forest of the country because of its propensity to use firewood for cooking. Despite the policy of using butane and the tendency to promote "clean" energy at State level, fuelwood is by far the most widely used fuel in Abidjan. Until now, the social determinants of the continued use of firewood in these bakeries have rarely been considered.MethodThis study used a qualitative approach and the main data collection techniques used were semi-structured interviews, observation, and literature. Different interview guides were sent to two types of actors such as state and non-state actors. At the state level, sampled actors was determined through "snowball" sampling technique. Thematic content analysis was the technique used to analyze the data collected from interview guides.ResultEnergy transition in the subsector of bakery in Abidjan is hindered by the plurality of actors and the lack of clarity in the energy governance led to the higher consumption of firewood and other practices developed around bread production.ConclusionThree elements which structure the adoption of clean energies in bakeries in Abidjan which are the multi-level political willingness of the State and its long-term bilateral and multilateral partners, the immediate social pressure linked to the wood resource and the availability of infrastructures

Most of the so called developing countries are located in tropical and/or sub-tropical regions whilst in contrast, most of the developed countries are in the temperate climate zones. It is expected that a huge increase in the future global energy consumption will be caused by the demand of the developing countries. Caused by the favourable climate conditions in tropical and/or sub-tropical regions the average productivity of biomass is 4 – 5 times higher than that of biomass grown in the temperate regions. Many of the developing countries today are agricultural and agro-industrial countries producing huge amounts of agricultural residues and wastes that can be used as source for energy generation. It is estimated that if only all process-based agricultural residues alone would be used, they could contribute between 25 % and 40 % of the total primary energy demand in such regions [1]. Until now, the huge amount of agricultural waste generated each year in developing countries is a headache for farmers, who are obliged to get rid of it. Open field burning and improper disposal are omnipresent in many regions and pollute the environment. Converting such waste into bioenergy such as biogas by using anaerobic digestion technologies represents an alternative treatment with a promising potential. Such treatment prevents pollution, is producing valuable and climate friendly energy and will contribute to nutrient recovery by using the digestate as fertilizer. The paper will introduce some of the most promising agricultural residues in tropical and subtropical regions which can be used as substrates or co-substrates for biogas production. Results of a research project carried out in Costa Rica will be used as a case study to show the potential of two of the major agricultural residues (pineapple and banana residues) as sources for biogas production. The opportunities and prospects for the dissemination and implementation of new and more developed technologies to improve the efficiency of the technologies will be shown.

Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

This paper explores the charitable work of Buddhist women who work as petty traders in Hồ Chí Minh City. By focusing on the social interaction between givers and recipients, it examines the traders’ class identity, their perception of social stratification, and their relationship with the state. Charitable work reveals the petty traders’ negotiations with the state and with other social groups to define their moral and social status in Vietnam’s society. These negotiations contribute to their self-identification as a moral social class and to their perception of trade as ethical labor.
